Various types of bedsheet holders are known in the prior art. However, what has been needed is a bedsheet anchor system including a triangular flat base with two legs, a curved hypotenus leg, a top surface area, and a bottom surface area. What has futher been needed is a strap knob on the bottom surface area of the triangular flat base so that an elastic strap can connect bedsheet anchors placed on each of the four corners of a bed. What also has been needed is a pair of triangular planar members, with each of the pair having an exterior area and an adjustable panel with adjustable serrated teeth. Each of the pair of triangular planar members is affixed to the legs of the triangular flat base. What has finally been needed is a series of notches and hooks on each triangular planar member that hold in place a top bedsheet and bottom bedsheet. The bedsheet anchor system is thus uniquely structured to not only better secure an edge of a bedsheet to a bed, but to prevent the tearing of the bedsheet during the securement process.
